ELEVATORS
U.S. Navy shipboard elevators are either the
electromechanical winch type or the electrohydraulic
ram type. Elevators are classified by their functional use.
The following designations are typical of elevators
installed in Navy ships:
l Cargo elevator
l Weapons elevator
l Ammunition elevator
Figure 8-5.—Auxiliary ship elevator.
l Personnel elevator
l Medical evacuation (MEDEVAC) (casualty)
elevator
l Aircraft elevator
Some elevators serve several functions. For
example, aircraft elevators are used to move weapons,
cargo, personnel, and support equipment. Weapons
elevators can serve as cargo elevators and can be used
to evacuate personnel casualties in a mass or medical
emergency situation. Figures 8-4, 8-5, and 8-6 illustrate
some of the types of elevators aboard U.S. Navy vessels.
Pay particular attention to the location of components
and safety devices on each type of elevator.
The complexity of elevator systems is increasing
and so is the degree of maintenance and training
required to keep them operational. It is a must that you
qualify and pass a PQS, Ordnance/Cargo Elevators,
Operation/Maintenance. Only qualified personnel can
work on elevators. When doing an elevator maintenance
